FPGA Register
Der FPGA enthält ein paar Register, die über den SPI Bus von einem Microcontroller geschrieben/gelesen werden können. Mithilfe dieser Register werden alle Blöcke, die implementiert wurden, konfiguriert.
SPI Kommunikation
Register Schreiben
Um ein Register zu schreiben muss zuerst der Opcode 'w' (0x77) gesendet werden, dann die Registeradresse und zu Letzt der neue Wert.
Beispiel: Register 0x0B wird mit 0xB0 beschrieben
